GAR-CONTROLLING DEVICE.

Application led March 16, 1923i. Serial No. 625,605.

loaded cars or trucks from a dry kiln or thev like.

The object of the invention is to provide a device of this character which will automatically brake the cars of the train and un-v couple them one by one, the brake'being set for engagement with the next lsucceeding car by the car previously uncoupled whereby the cars may be safely and speedily taken from the dry kiln. p

Another object is to provide a device of this character which is of simple and durable construction, reliable in operation and easy and comparatively inexpensive to man-v ufacture. i

Other objects and advantages of the invention reside in certain novel features of the construction, combination and arrangement of parts which will be hereinafter more fully described and particularly pointed out in the appended claims, reference being had to the accompanyingv drawings formingpart of this specification, and inl which: p

Figure 1 isa view in side elevation, showing .the preferred embodiment of the inven tion and showing the parts set at ythe start of the removal operation;

Figure 2 is afview similar to Figure 1, showing. the second phase of the.r operation;l Figure 3 is a plan View, parts being broken away for the sake of illustration;

Figure et is a fragmentary perspective view, illustrating the car operated mechanism for setting the brake; and

Figure 5 is a View in section on line 5-5 y of Figure 2.

Referring to the drawings the numeral 10 designates a track or railway which extends into the dry kiln, the door of which is designated at 11. This track 10 is usually built on an incline so that when released the cars will move by gravity out of the kiln. The cars or trucks of the train are run on the track 10 and are designated at 12. These cars 12 may be of any conventional or desired construction'and preferably include a'frame lhaving end cross bars 14 and running gear made up of wheels `15 and axles 16. i v

The cars are coupled by means of weighted levers 17 pivotally mounted,` as at 18,

on the `frame of the car at one end thereof l' and having a laterally offset hook 19 adapted to engage the end cross bar 14 of the ad-4 jacent car to couple the cars together. It is to be understood that at least one such lever 17 is carried by each car or truck and these levers 17 are so weighted as to throw their hooks 19 into engagement with the cross bar 14 of the next adjacent car.

A bed plate 25 is suitably secured on the` railway adjacent the door. of the kiln and it is arranged in between the rails of the track.. A pedestal includingspaced standards 26 is suitably secured to the bed plate, the stan'd. ards being located anequal ,distance from the centerline of the track andbeing ofk such a height that the axles of the car readily clear or pass over them. A broad flat and elongated bar 28 of metal or other material, suitably faced byleatlier or the like if found desirable is pivotally connected at lugs 30. This bar 28 constitutes a brake be` ing engageablewith the axles of the cars of ENCE/ff one end7 asiat 29, to the standards 26 and the thetrucks when set toretard and arrest the motion ofthe cars, V.the lugs `30 affording the fiat tops of the bars on the axles is usual-Y ly sufficient to arrest the motion ofthe cars but in order to preclude any 'possibility ofv the cars gettingaway the lugs 301 areV provided Vand as indicated areengageable with the axles to serve as stops to positively arrest movement of the axles and consequently of the cars.

Car operated or actuated vmeans is provided for set-ting the brake, this means being susceptible of manual operation for releasing the brake when desired. Preferably this means comprises a rocker arm 35 pivotally mounted on a bracket or pedestal 36 secured to the bed plate. The rocker arm 35 has its ends bifurcated and in one of the bifurcated ends a roller 35a is rotatabl Y mounted, the roller being engageable wit the underside of the brake bar 28 at the end thereof adjacent the lugs 30. The other bifurcated end of the rocker is pivotally secured to one end of a connecting rod 37. The other end of the connecting rod 37 is pivotally connected to one end of a lever 88, the lever being fulcrumed or pivotally mounted vbetween its ends, as at 39, on a bracket 40. rEhe bracket 40 is provided with a stop il which limits the movement of the lever in a clockwise direction as viewed in Figures l, 2 and 4. The shoulder 4l is preferably arranged to engage the lever 38 to stop its movement when the rocker 35 has been thrown t0 a vertical position, or to a position just past the vertical in a counterclockwise direction, as viewed in Figures l and 2 so as to thereby hold the brake bar 28 in set position. @n its upper end, the lever 38 is enlarged, asat 38dL and may be weighted if found desirable. As before stated the axles of the cars clear the pedestals 26 and also clear the end of the bar connected thereto but the rocker 35 elevates the end of the bar 28 which it engages well above the level of the pedestal so that the bar engages the axles of the cars at a point intermediate its ends, the rocker being properly proportioned and mounted for this purpose.

In operation when it is desired to remove the cars from the kiln the door ll is moved aside or opened and the lever 38 manually moved to the position shown in Figures 1 and 4. The first car of the train that is the car disposed adjacent the door l1 is then given an initial impulse and the train starts to move by gravity along the track in the'direction of the arrow. This movement of the train will bring the weighted coupling lever 17 of the second car into engagement with the pivoted end of the bar 28 so as to tilt this coupling lever and thereby uncouple the first car of the trainas shown in Figure 2. As the first car of the train continues to move its coupling 17 will strike the lever 38 and move the same from the position shown in Figure l to the position shown in Figure 2. This actuation of the lever 38 will be transmitted to the rocker 35 through the connecting rod 37 and will swing the rocker to a vertical position or to a position just past the vertical in a clockwise direction, as viewed in Figures l and 2, the rocker being limited invits movement tothis position by the coaction between the lever 38 and the shoulder al. l/Vhen the rocker 35 is moved thus it elevates the free end of the brake bar 28 and brings the upper surface of the same into engagement with the axle of the cars so as to arrest or retard the movement of the cars. ln order to release the next cai' of the train the lever 38 is set manually and the operation is repeated. In this manner the cars or trucks may be safely and speedily removed froin the kiln and the train is auto` matically stopped as each car is released, the uncoupling of the released car and the braking of the train being automatically effected.

I claim:

l. The combination with a track and a train of cars thereon, and a releasable coupling' for the cars of the train, a brake carried by the track and cooperable with the cars, and means operated by the cars of the train for setting the brake, the brake also being engageable with the releasable coupling of the cars for successively uncoupling the same.

2. rllhe combination with a track and a train of cars thereon, a weighted coupling lever pvotally connected to each car and having a hook engageable with each adjacent car, the coupling depending from the car to which it is secured, a brake carried by the track and cooperable with the cars, said brake being engageable with the coupling for uncoupling the same, and means ioperated by the coupling of the uncoupled cars of the train for setting the brake.

3. In a device of the character described,

la bed plate, a pedestal mounted on the bed plate, a brake bar pivotally secured at one end to the pedestal and having a pair of stop lugs at its opposite end, and means for setting the brake bar including a rocker engageable with the underside of the brake bar, a car operated lever and a connecting rod between the car operated lever and the rocker.
